To all whom it 11mg concern:

Be it known that I, ELMER A. SPEER'Y, a citizen of the United States,residing atOleveland, county of Ouyahoga, and State of Ohio, haveinventeda new and useful Improvement in Power-Gearing for Trucks, ofwhich the following is a full, clear, and exact description.

lily invention relates to powe1--t1-ansmitting devices forvehic1es,moreespeeiahjyrailwaytrucks; and it consists in certain devices fortransmitting power, between the rotatin axles of such trucks or betweena motor or motor devices and such axles, whereby the normal flexibilityoft-he truck is not interfered with, the construction allowing-0f theindependent movement of the axles with refare used in connection withshort-radius,

curves, rough track-crossings, and thelike.

It furthermore consists in certain details of construction which tend tocheapen such der vices and render them more efficient.

It is fully describedin the specification and pointed out in thecla'inis, and illustrated in the accompanying drawings, in which- Figure1 is a plan view of a railway-truck with the power-transmitting devicein place, showin some portions of the gearing in tion and thetransmitting device in outline. Fig. 2 is a front elevation of thepower-transmitting device. Fig. 3 is a side elevation of the same. Fig.at is a side View of the balllink, partly broken away. Fig. 5 is a largesection of said link and the ba ll-and socket bearing on line a: 33,Fig. 2. Fig. 6 i's'an elevation'of the driven member; Fig. 7, anelevation of the driver. Figs. 8, 9, and 10 illustrate details of theflexible driving device. Fig. 11 is a top plan view of thetransmi'ttingdevice when the shafts'a're separated axially. Fig. 12 is a sideelevation of the same, and Fig. 13 i'sja detail showing the cushioningdevice for the bars which support the motor.

Let A A,Fig. 1, represent a truck-frame mounted uponbearings BB, &c., onthe'out'e'r extremities "of the axles O O, supporting niitting device,preferably a beveled gear and pinion, which are suitably housed ingear-casings (indicated at D D) geared upon axles by journal-bearings D.The pinionshaft of the gear is journaled in suitable bearingsaisolocated Within the gearhousing D at point D which forms, preferably, anintegral portion of such gear-h'oi'is'in'g' and receives support on across-bar X of the truck-frame A. The'pinion-shaft protrudes from its'journal sufficiently for the proper securing of. the hub 11, carrying anarm or arms H, Which constitute the driven element and are illustratedin detail in Fig. 6. A short piece of shafting, resting in suitablebearings H, is mounted upon cross-pieces I I, secured to the truck,preferably by elastic cushions or supports 1. This shaft may or may notconstitute a portion of the motor J, but it is preferably a driven shaftreceiving motion from said motor. Supposing, however, that it forms apart of such motor, the motor provided with the bearings H is suitablysupported on the cross-pieces I, which preferably are fiat bars withtheir greatest dimension vertically disposed and relatively somewhatflexible lengthwise of the truck, as is clearlyshown in dotted lines inFig. '1, thereby allowing the motor freedom'of movement in thislongitudinal direction dependent upon the amount of elasticity of saidbars I. It will readily be understood that such movement will take placewhen the vehicle strikes any obstruction, either small 'or great, orstands upon a grade. The inertia or momentum of the mass making up "themotor J will be found to constitute afoice acting to flex the bars I inthe manner de-' scribed. As this longitudinal movement of the driving orarmature shaft takes place the extremities thereof close in upon orrecede from the adjacent extremities ofthe pinions'ha fts. In Figs. 2and 10 will be found details of a structure constituting a flexibledriving device organized to connect the extremities of the saidpinion-shaftsin such a manner asto provide for such longitudinalmovement of said driving or armature shaft and at the same time notinterfere in the least with its proper functions as a power-transmittingdevice. This device is substantially ical socket at-each end fitting thepinsP and R, substantially as described.

4. ha motor-truck, the combination with the axles, of shafts arrangedlengthwise of the truck and geared to said axles, cross-bars supportingthe inner ends of said shafts,other cross bars between the shaftsupporting cross-bars, said latter bars being rigid vertically, butadapted to flex horizontally, in a direction lengthwise of the truck, amotor supported on said flexible cross-bars, and comprising alongitudinal driving-shaft, and flexible power-transmitting devicesconnecting each end of said shaft With an adjacent geared shaft,substantially as described.

In testimony whereof I have hereunt signed my name.
